I (30) have been seeing a girl (26) for 5 months. We met on a dating app. She refers to me as her boyfriend but we have never had the relationship talk. She told me she really likes me but doesn't do emotions. She also said we'd have to meet each others' parents at some point. She told me she went through two bad break ups several years back and for the past 3 years she has 'dated' but not been 'too bothered' about a relationship.
First month had been great ... just innocent dating and nothing more physical than kissing, hand holding and cuddling.
We are then intimate and she tells me that I won't need to use protection and shows me the implant. This was a massive alarm bell for me. One night in bed she randomly tells me that a guy has been sending her explicit messages. She shows them to me and there is some overlap with our first dates but nothing too recent. The string of texts shows one reply from her which is flirty. There are several others from him which as very lewd but nothing from her. To me it looked as though she had deleted her replies as one text said "night xx" two days after the previous one. When I asked why she showed me these, she said she thought I knew him ... I couldn't bring myself to say anything ... it kept me awake all night though.
She is very much a party animal whereas I am much less of one, especially when in a relationship. She recently came back from Magaluf which I also didn't ask too much about. She also accrued some debts which are now dealt with.
Fast forward to this weekend - we go out with a couple she knows. She spends a lot of the night talking to guys but I figure they're friends. She randomly then says it's time for me to leave the club as I don't drink often. I decide to stay and nothing more is said. Outside the club a guy asks her if she is going to take his friend home repeatedly. I get angry and push his friend. I don't remember much after that but the guy had walked off thankfully. Again I can't sleep. I am wondering whether this is an old flame or someone she has been in contact with since we have been together.
She often tells me how people have bought her drinks too and how guys have cheated on her in the past. I don't know if she just doesn't get what she is doing or whether it's designed to make me feel insecure and her more secure. I think I may have some issues with jealousy and insecurity but I don't know where to turn? GP? Counselling? For the past few days I have found it difficult to concentrate and get out of bed. Please help!?
